Quad-winged hawk

Summary
The Quad-winged hawk (a.k.a quadhawk) is a common sight across the continent of Geminus Minor, but have been known to roost in the Arcanus archipelagos from time to time. Quadhawks derive their name from their unique four-winged structure; a peculiarity even amongst the hodgepodge gatherings of species on Eltar. It is however a feature that seems to work in their favour, as it has allowed them to thrive in the thick woodlands of Geminus Minor far more than their more contemporary cousins, with the extra pair of wings providing much swifter manoeuvring, acceleration and deceleration that offsets their slower speed. Whilst in more open & less sparse wooded areas this is a detriment, it's a boon on both the Geminus continents, though the greater number of predator species in Geminus Major has seemingly prevented the quad-winged hawks from thriving there in too great a number.

Appearance
Averaging around 30-40cm, quadhawks are commonly coated in dark brown and grey feathers with some uncommon instances of tawny and redder hues. When it comes to the titular wings, these are split into two pairs: the main wings with the wingspan on average being 3 times the length of the hawk's body (e.g. 90-120cm) whilst the second pair (referred to as rudderwings) have a wingspan are closer to 2 times the length (60-80cm). When perched, the rudderwings tuck under the main wings at a somewhat diagonal angle so the ends of the rudderwings are visible near the top of the hawk's legs, and when in flight they extend mostly level with the body, acting as an extra pair of wings when speeding up or slowing down, and as a form of extension to the tail feathers for tight manoeuvring. 

Diet & Behaviour
As with other hawks, the quadhawk is carnivorous and solitary in nature, predominantly preying on smaller herbivores native to the area, though they have been known to eat smaller birds on occasion as well. Due to their adaptations being suited for tighter and denser environments, quadhawks have much better hearing than most hawks, often opting to take advantage of their manoeuvrability to surprise their prey by making tight turns from behind cover and catching them before they can fully react.
Observations regarding their mating rituals suggest that most quadhawks are monogamous, and will settle with a partner for life. On meeting a potential mate, the pair will roost on nearby trees and the male fully expands their wings whilst calling out. If the female reciprocates, she will shortly after launch herself from the tree and dart through the wooded areas whilst the male tries to catch up. Whilst evidence suggests catching up to the female isn't always necessary, only a few exceptions have arose where the male didn't at least keep within eyesight of the female. It has also been found that whilst some other breeds of hawk are sexually compatible with quadhawks, these relations have seldom produced offspring capable of flight, often with missing or malformed wings that unfortunately leads to their death when attempting to leave the nest.
